Since the conveyers in the threshing cylinder iit-l closely within the side walls ofthe thresher housing, it isnecessary thatthesup-v porting means forthe upper. ccnveyer, which enables the upperlconvjeyer to be adjusted with respect to the lowerconveyer .when closely adjacent the lowerlconveyer and also tobernoved away from the lower conveyer, be 'mounted in the lside walls of the thresherhousing The present application has to do with a supporting means oil'fthis sort.

During normal operation of thethresher construction, crops to be threshed are fed along the lower conveyer I2 toward theY threshing ,cylinderI Il and are regulated in depth by the upper contion and for moving the upper conveyer away from the lower conveyer for cleaning, said means comprising 'a carrier for the upper conveyer detachably connected to the upper conveyer and extending through and along the outer side of one wall, and means forming a slidable and pivotal connection of the carrier with the outer side of thesaid one wallfor providing the upper conveyer movement toward and awayfrom the lower conveyer by virtue of the slidable connection and for providing detachment of the carrier from the upper conveyer and withdrawal of the carrier to theouter side of said wall by virtue of the pivotal ,connection .y .2.y Inan assembly comprising a housing having a wall, a threshing cylinder within the housing, a

lower conveyer within the housing leading toward veyer I3, which is quite near the lower corweyerH I2 at its inner end adjacent the threshing cylinder I I. As the amount of material movingf toward the threshing cylinder I I varies, the inner endf'of the upperconveyer I3 may move up and down against the resultant action of the spring4 38',"'sin,ce the carrier 25 may slide with respect to the holder 3|. f

When itr is desired that laccess be provided to the space between the inner ends of the conveyors I2 and I3 and that accordingly the inner` endof the upper conveyer I 3 be moved away from the inner end of the lower-conveyer I2, theupper end 28 of the carrier`25, serving as aA control handle, is grasped and the Acarrier 25 is raised so that the notch 23 is disengagedfrom the lower edge ofthe slot 22 inthe side member I9, and the end portion 24 of the carrier 25 is swung out of the, slot 22,and outwardly through 'the slot 261m the sidewall III to the outer 'sidepf the side4 wall., Thissame procedure is followedfor the carriers 25 at both sides of-'the conveyer Illfand' then the Aconveyer I3 l is free tov beswung upwardly so that itsinner end is moved away from inner end of the conveyer I 2. The upward swinging of the conveyer I3 takes place about the bolts. 2l!` as an axis andsothe upper conveyer I3 loosensin the upward swinging.

From the foregoing description it willbe appar-.- ent that a ,new ,and novehsuppprting meanslias been provided for a. .t1iresherconstruction. supporting means'enables an upper conveyer of a pair of conveyersleading toa threshingrcylinder `to be adjustably supported in close proximity` to the lower conveyer'ffor upward and. .downward movement inoniornration with variationin flow.`

of crops tothe threshing cylinder.` The supporting Vmeans is also so arrangedthat it'maybelreadily disconnected from ,the-upper,.conveyer so that the upper conveyer maybe swung away fromY the lower conveyer foracoess to the space bet-ween-theV conveyers.
